A new type of cloud has been discovered

It doesn't happen very often that new clouds are discovered. But this one is new one for the weather record books

Sprites are extreme high altitude lightning

I actually first about sprites when my students were doing our research projects. Sprites how are extreme high altitude lightning displays. These remarkable electrical displays can sometimes be photographed as this one was at 80 km. See the photo and directions how to do sprit chasing and look for the phenomenon.

Noctilucent clouds are heading further south

Are these strange clouds the result of volcanic eruptions, global warming or something else. Find out further information about these strange clouds

Noctilucent clouds

These mysterious  electric blue clouds started showing up in the US summer in  Canada and northern parts of Europe. Scientists still don't know how they form.They are 45 and 54 miles (75 and 90 kilometers high but if you  are in  the right high latitude area, they supposedly easy to see.
 This year they are now being observed in Vermont, Wyoming and Michigan. Be on the look out for them and post if you see them.

Shelf Cloud Over Saskatchewan APOD

Shelf Cloud Over Saskatchewan, Canada APOD 1/22/2008*
Beautiful photo of Shelf Cloud Over Saskatchewan by Jeff Kerr shows a beautifully orange lit shelf cloud on August, 2001.
Nice explanation of the weather activity and how this formation differs from wall clouds.

You think it is hot on Earth- Life is Hell if you lived on Venus

If you go out and look in the East before sunrise you will see a very bright "white star." It's actually the planet Venus, the 2nd planet from our Sun. Clouds reflect much of the light but also make it impossible to take look at the surface of Venus. These clouds are not made of water vapor but sulphuric acid. But that's not all.

The carbon dioxide rich atmosphere traps much of the heat. Basicly this conditon creates a runaway Greenhouse gas condition in which all the heat which enter through the clouds is trapped. The temperature is over 700 Fahrenheit so it is like"Hell on Venus."

Two Russian Venera spacecraft did land on the surface and sent back photos of the surface which instantly told us how arid this desolate planet is. But we did not know why it is so dry. Now we have answers.

Europe's Venus Express spacecraft has communicated an important discovery: the solar wind dries out Venus. Unlike Earth, Venus has no global magnetic field to deflect particles from the sun. When radiation from the Sun called "solar wind" hits Venus, it decreases the upper atmosphere. Hydrogen and oxygen atoms fly into space, removing water from Venus. The process makes conditions even hotter and worse by making the climate dryer planet.
Here is further information.

Rainbow cloud over Colorado

I have seen clouds like this within the last few months but did not have my camera handy. In any here is a a great photo posted 11/25/2007 (if not this date look in archives).

Fire Rainbow

4/4/2007
Students will learn about
(EOAS1) weather and clouds
(EOAS2) spectrum
(EOAS3) how light is refracted (bent) by substances and creats different colors


This is truly a phenomenon of ice not fire. But it does deal with light.

June 19, 2006—It looks like a rainbow that's been set on fire, but this phenomenon is as cold as ice.
Known in the weather world as a circumhorizontal arc, this rare sight was caught on film on June 3 as it hung over northern Idaho near the Washington State border
